Mistress by agreement

From the moment tycoon Kingsley Ward walks into Rosie's office, she recognizes the sexual invitation in his eyes. But when they sign a business agreement and Kingsley makes it clear he wants Rosie as part of the deal, she's outraged! Kingsley's initial purpose had been business–not pleasure. But Rosie is beautiful and, unbelievably, she seems immune to his charms! Kingsley decides he'll pursue her until he wins her as his mistress…and he's never lost a deal yet! Sweet but some baggage. Without help, not sure it is possible to get out of a tub full of water with a foot cast on. let alone getting back into said bath with a cast on the foot. Please, I need instructions with diagrams.
